Is there a decent enough formula for road bike TT + Xcm = mtb TT that I can use as a starting for looking at used MTB's?
Thx!

My top tubes between road and mountain bikes are fairly close for ETT, my road bike is actually a tad shorter than most of my mountain bikes. Depends on the mountain bike as well as your preferences. Go test ride some in the type of mountain bike you're interested in and note top tube/stem/bar setups for an idea...
What kind of riding do you want to do? Good luck on having used mountain bike ads tell you what the ETT (or even manufacturer's measurment) was....
